Attributes

Attributes provide a powerful method of associating metadata, or declarative information, with code (assemblies, types, methods, properties, and so forth). After an attribute is associated with a program entity, the attribute can be queried at run time by using a technique called reflection

Attributes have the following properties:

• Attributes add metadata to your program. Metadata is information about the types defined in a program. All .NET assemblies contain a specified set of metadata that describes the types and type members defined in the assembly. You can add custom attributes to specify any additional information that is required..
• You can apply one or more attributes to entire assemblies, modules, or smaller program elements such as classes and properties.
• Attributes can accept arguments in the same way as methods and properties.
• Your program can examine its own metadata or the metadata in other programs by using reflection.
